T 0 all lwhom it may concern Be it known that I, GASPAR BUELLESBAGH, a citizen of the United States, and a resident of New York, borough of Bronx, county 0f Bronx, and State of New York, have invented a certain new and useful Improvement in Convertible Beds, of which the following is a full, clear, and eXact specilication.

This invention relates more particularly to a class of furniture.

My invention has for its object primarily to provide a bed designed to be employed in hospitals, sanatoriums and elsewhere whereby the occupant may rest in a lying position, or may be arranged in a sitting or reclined posture without being removed therefrom, and which is adapted to be readily converted to a form somewhat similar to a reclining chair and vice versa. The invention consists essentially of a support having a head section and having a detachable foot section, and on the support is held a frame for holding a mattress, or other upholstery,'the said frame being -divided into a plurality of hinged members one of which is stationary on the frame to serve as a seat when the bed is converted to a chair, while lthe other sections are adapted to be adjusted upwardly and downwardly to various positions relative to the stationary member as well as to the support for converting the bed to a form somewhat similar to a reclining chair as occasion requires.

Other objects of the invention are to provide operative mechanism whereby the hinged members of the frame may be manually adjusted; and to provide a convertible bed of a simple, eiiicient and durable construction which is susceptible of being made in di'erent sizes.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings forming a part of this specication in which similar characters of reference indicate corresponding parts in all the Views, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is a side elevation, partly broken away, of one form of convertible bed embodying my invention.

Fig. 2 is a top plan of the support of the bed with the mattress removed therefrom.

Fig. 3 is a side elevation of the bed when converted into a reclining chair form.

Fig. 4 is a detail sectionall view, partly lroken away, taken on the line IV-IV of Fig. 5 is an enlarged section taken on the line V-V of Fig. 1, showing a form of device for detachably fastenin together the head and foot sections of the ed, and

Fig. 6 is an enlarged fragmentary View showing a side elevation of the fastening device.

The convertible bed has a support 10 which may be composed of a head section 11 and a detachable foot section 12. The head section 11 has two spaced side bars 13 and 14 one of the corresponding ends of which are connect/ed by a cross-bar 15, while between the other ends ot the side bars is a second cross-bar 15a. At the corners of the side bars 13 and 14 with the cross-bar l5 are provided posts, as 16 and 17, of lengths so as to extend some distance below the bars -as well as projecting a suitable distance above the bars. The body of each of the posts may be tubular, and each post is divided into a lower member 18 and an upper member 19. The members of each post may be detachably fastened by providing in the lower end of the upper member a projecting fixed plug, as 20, which is removably inserted in the upper end of the lower member of its post, and between the lower membersy 19 oi the posts is a transverse bar 21 arranged some distance below the side bars 13 and 14. The foot section 12 of the support has two side bars 22 and 23 spaced at a distance similar to the distance between the side bars 13 and 14 of the head section 11 so that the bars of both sections are on alined abutting arrangement, and these side bars of the foot section are considerably less in length than the side bars of the head section. Between the ends of the side bars 13 and 14 of the foot section in proximity to the side bars of the head section, is a crossbar 24, and the opposite ends of the side bars 13 and 14 maybe connected by another cross-bar, not shown. At the corners of these side "bars with the cross-bar of the foot section 12 are posts 26 and 27, and the lower parts of the posts are connected by a transverse bar 28. The side bars of the head andfoot sections 11 and 12 may be detachably fastened in any desired manner, though these sections are `preferably connected by fastening devices, as 29, Figs. 5 and 6, both of which are similarly formed. Each of the fastening devices 29 has a plate 30, and one of these plates is sec'uredyoneach of the side bars 13 and 14 of thel head section 11 of the support at the ends of the side bars. In the surface of the plate 30 of each device is a groove, or recess, as 31, and

through each of these plates centrally of the groove as Well as through each of the side -bars are registered threaded openings 32 for reception of a set screw, as 33. Each of. the fastening devices 29 also has a second plate 34, and one of these plates is secured on each of the side bars 22 and 23 of the foot section Yl2 in opposed relation to the plate 30 of its respective fastening device. Projecting from the second plate 34 of each fastening device is a tongue, or linger, as 35, and these tongues are adapted to beremovably inserted into the grooves 31 of the plates 30 when the head section and the foot section are detachably connected, while through each of the tongues 35 is an opening 36 adapted to be registered with the threaded openings 32 of plates 3() of the .fastening devices for the passage of the set screws 33. To separate the foot section 12 from the head section 1l of the support the screws 33 are removed vfrom the openings in the fasteningv devices, and the tongues 35 are withdrawn from the grooves31 by guiding the foot section of the support accordingly from the head section, and by reversely moving the foot section the tongues will be rearranged in the grooves for reinsertion of the screws in the registered openings 32 and 36 of the plates of each of the fastening devlees.

Serving to permit a person occupying the be'd to be in a lying position, or to be arranged in asitting or reclining posture, on the support 10 is an adjustable frame, as 37, having twonormally disposed side bars 38 and 39 which are spaced apart at a distance corresponding to the space between the side bars of the head section and the foot section of the support, and these side bars of the frame are shorter than the lengths of the side bars of the support. The frame is divided into a seat section 40, a leg section 41, a back section 42, and a head section 43 all of which are adjustable with relation to each other when the bed is convertible to a form of chair. The seat section 40 is provided by separating corresponding central parts of the side bars 38 and 39 of the frame, and from the opposed endsot these bars are two upwardly projecting short bars, 44, 45 and 46, 47, the upper ends of which are hinged toat 49', to the side bars of the support for fastening the seat section in a stationary position on the support. The leg section 41 of the frame is provided by separating corresponding parts of the side ybars 38 and 39 at parts thereof in proximity to the junctures of the head and foot sections of the support 10 of the bed, and the opposed ends of each of these separated parts of the side bars of the frame are adj ustably connected by hinges 50 and 51 arranged on the top of the bars, while these opposed ends of the bars are cut away in thel fashion of a miter, as at 52, to allow the leg section to be swung downwardly and upwardly right angularly with relation to the seat section 40, as will be hereinafter more fully described. The back section 42 is provided by securing on the central portions of the side bars 38 and 39 of the frame the lower ends of upwardly extending short bars 53 and 54 and the head section 43 is provided by hinging, at 55 and 55a, to the bars 53 and 54 the upper ends of two downwardly fprojectingbars 56 and 57, the lower ends of which are secured to one of the corresponding ends of two longitudinal bars 58 and 59 adapted to be swung upwardly and downwardly to and from the side bars 38 and 39 of the frame 37. All ofthe upwardly extending hinge bars of the frame 37 are of lengths so that their upper ends` are on alinement, and these bars are arranged vas well as the frame being constructed so that the seat section 40, leg section 41, back section 42, and the head'section 43 are preferably similar in lengths, as shown. The adjustable frame 37 is supported in spaced relation abovethe side bars 13 and 14, of the support 10 by arranging on the underside of the sectional side bars 38 and 39 a suitable number of transverse bars, as 60, each of which is substantially the shape ofan inverted L, as viewed transversely, so as to rest on the` side bars of the, support. and i crosswise of the free ends of the parts of the bars 38 and 39 of the frame is a foot board, orbar, as 61. The seat section 40, leg section 41, back section 42, and head section 43 may be suitably upholstered, for example, by one or more springs 6,1, Fig. 4,

63, adapted to be manually operated. Th'e mechanism 63 preferably consists of a rod, or shaft 64 one end of which is journaled iny a bracket, or bearing, as 65. depending from the central part of a cross-bar 66 arranged on the underside of the side bars 13 and 14 of the support adjacent to the seat sections 40 of the frame. The shaft 64 extends under the head section 11 of the support 10 rearwardly of the posts 16 and 17, and the second end part of the shaft is journaled 1n a bearing provided in the bar 21 between the posts. On the end of the shaft 64 extending beyond the posts of the head section of the support is a handle preferably in the form of a wheel 67 to allow the shaft to be manually rotated, and on the shaft contiguous to the bearing 65 is a Worm 68. Meshing with the worm 68 is a segmental worm.

gear 69 which is held on a rod70 journaled in openings, or bearings inthe side bars 13 and 14 of the head section of the support of the bed, and this rod is of a length sothat its ends extend beyond the side bars. The rod 70 when revolubly turned operates two levers, as 71 and 72, each composed of a bar 73 having one of its ends held to the rod,

and the second end of each of the bars 73 is pivoted, at 75, to one end of a second bar 76. The second ends of the bars 76 are pivoted, at 77, respectively, to the side bars 38 and 39 of the frame 37 under the back section 42 so that when the wheel 67 is turned to revolve the shaft 64 accordingly the worm 68 will be revolved for rotatably moving the segmental worm gear 69 with the rod 70 to guide the levers 71 and 72 upwardly for elevating relatively to the seat section 40 and to the support 10 the back section 42 as well as the head section 43 of the frame, and by reversely operating these parts of the mechanism 63 this section of the frame will be lowered on the side bars of the support.. Serving to permit the head section 43 to be further adjusted vertically with respect to the back section 42 and the inclined parts of the side bars of the frame, on the side bars 58 and 59 of the head section 43 contiguous to their 'free ends are pivoted, at 78 and 79, the upper ends of two racks 80 and 81 so that the lower parts thereof may be swung backwardly and forwardly-lengthwise of the side bars 38 and 39 of the frame 37, and on the side bars of the frame adjacent to the free ends thereof are projecting lugs, or stops, as 82 and 83, adapted to be releasably engaged by the teeth of the racks. By guiding the racks upwardly one end of the head section 43 will be accordingly swung upwardly relative to the back section 42- as well as with respect to the inclined part of the frame 37, as illustrated in Fig. 3,'and by moving the racks into engagement with the stops 182 and 83 the racks and the head section will be held in adjusted positions against accidental movement. To allow the'leg section 41 of the frame 37 to be lowered with respect to the seat section 40, adjacent to the free ends of the side bars of the leg section are pivoted, at 84 and 85, the upper ends of two racks 86 and 87 both of which are curved in the shapes of arcs of circles so as to be swung upwardly and downwardly alongside of the side bars 13 and 14 of the support lO toward and from the underside of the bed,and in the path of movement of the teeth of these racks are lugs, or stops, as 88 and 89, projecting outwardly from legs 90 and 91 arranged on the underside of the side bars 13 and 14 of the support 10 in proximity to the devices 29 which detachably fasten the head section 11 with the foot section 12 of the support. When it is desired to lower the leg section 4l relative to the seat section 40 of the frame, the foot section 12 of the support is detached from the head section 11 after operating the devices 29, as hereinbefore explained, and the leg section of the frame is then swung downwardly from the seat section 40, as shown in Fig. 3. The racks 86 and 87 will be likewise swung below the bed so that their teeth will engage the stops 88 and 89. The bed will thereby be converted to a form similar to a reclining chair, and by reversely operating the various parts of the mechanism 63 the frame 37 will be readjusted on thesupport 10 in the manner shown in Fig. l. lFollowing the refastening of the foot section 12 to the head section 11 of the support 10 the article may be used as `a bed of an ordinary ty e, and on the lower ends of the posts 16, 1 26, 2,7 as well as on the legs 90 and 91 may be provided casters, or rollers v92 of desired makes to allow the bed to be easily moved from place to place.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, aS I am aware that modications may bemade therein, without departing from the principle, or sacrificing lany of the advantages of this invention,

Having thus described my invention, I
